To all whom it may concern' B e it known that I, ROBERT IjIiLPREcnL'a sub]ect of the German Emperor, residing at Lansing, in the county of Ingham and State 5 of Michigan, have invented certain new and useful Improvements in Suction Gas-Producers, 4of which the following is a specification, reference being had therein to the accompanying drawing. 1o T e invention relates to suction-'gas-producers, and has for its object the obtaining of a construction capable of beingformed in relatively small units.

In the present state of the art 'suction gasproducers are usually formed with a casing in which a mass of fuel is placed, the fuel being centrally fed tion for removing the gas being applied to the sides ofthe mass. With the resent conzo struction `the fuel is fed into til from the sides, and the gas is drawn off at the center. Furthermore, a relatively large chamber is formed' within the center of the mass of fuel in whichthe as generated is collected, and the extender? surface of this chamber is utilized for absorbing the heat from the gas and transferrin it to the surrounding mass of unburned el. A steam or vapor generator is also arranged within this central chamber.

In the drawing the producer is illustrated in verutical central section.

A is an outer casin the lower ortion of which is provided wit a iireproofP lining B, which is of a conical or a downwardly-ta ering form. C is a grate at the lower en of this lining, this being preferably of a` baslget frm and depending into an ash-pit chamtween the inner easing F and the outer casing -A. The'lower end of the casing F is some 5o distancel above the grate, so as to ermit the fuel passing downward through t e annular which'is arrang conduit K., which conduit is connectedwith into the casing and the suc' e chamber E is a fuel-hopper at the upper end of thev as a conical' entire grate area. f

At the upper end, of the casingF is arrangrl. a water-rece tacle H, and the steam enerl ated therein y the heat of the ases wi pa'ss" .to a -vapor- This conduit is preferupward in the conical casing discharge condui I. ably provided with a .discharge-nozzlegJ ,1

' ed as an injector within thel the upper end of thefuel-chamber between the casings' F and A. gases passing off pelled by the jet from the-nozzle J throu h the conduit K, Which leads chamber D beneathv the grate. This conduit K also connects with the aireinlet conduit L,-`

which is' mixed with the vapor and gas entering the ash-.pit chamber.

With the "construction described a `relatively small mass of fuel is held within the casing A at an one time, and the device .is Operative for t small amount of as, which has not. proven practicable with t e constructions heretofore used. The suction-conduit M, which connects with the chamber within the casing F, is connected with the engine, and whenever suction is produced the required volume of air, steam, and distilled gas is drawn into the ash-pit chamber D and thence through the grate and mass of incandescent fuel supported thereon into the'central chamber.

It will be noted that the casin F forms, in effect, a suction-hood arrange above the grate and that by reason of the tapering form of the lining B the fuel is' fed between said patented June' as, 190e. A'

downward to t e e production o f a relatively.

space between the casings tonspread over fthey Thus any distilled from the fuel will be pro? hood and grate'from the periphery thereof toward the center. Thus the layer of fuel between the hood and grate is maintained of uniform thickness. What I claim as my invention is- 1.l A suction gas-producer comprising an outer casing, an inner casin open at its lower end and spaced from sai outer casing to form an annular fuel-chamber therebetween, `a grate beneath the opening of said inner casing, a vaporizer within said innercasing', a

and a sucfuel-hopper above said vaporizer,

tion-conduit connected with the gas-chamber within said inner casing.
